Abstract: PRESSURE-BALANCED WELL SERVICE VALVE            Abstract of the Invention.  A well service valve used primarily for the injection of closely controlled batches of well treating fluids into low pressure formations utilizes a biased one-way flow valve in a tubing string to hold the treating fluid in the column until the tubing is pressurized to open the valve and expose flow ports in the wall of the tubing to the formation. A partial pressure-balancing of the flow valve allows the use of a lower biasing force in the flow valve, thereby greatly increas-ing the reliability and useful life of the valve.   1a

Abstract: CONTINUOUS METHOD OF AND APPARATUS FOR MAKING          BARS FROM POWDERED METAL         Abstract of the Disclosure Powdered metal is continuously introduced into a horizontally disposed die cavity in discrete quantities and compared in o bar segments to form a bar.  The cavity has a fixed cross-sectional area and is open at both ends, except during the initial compaction when one end is closed.  After formation of an initial length of the bar, the frictional resistance between the length of bar remaining in the cavity and the cavity wall is relied on so that the length of bar remaining in the cavity serves as a stopper for subsequent compactions of the discrete quantities of powdered metal.  The bar is forced out of the cavity upon the formation of subsequent segments and is passed through an induction furnace for sintering, and may be further processed through a swager, all preferably in a continuous operation.  Also provided is means for varying the quantity of powdered metal introduced into the die cavity so that the bar lengths formed from the discrete quantities of powdered metal are compacted and bonded into a bar of substantially uniform physical characteristics along its length.

Abstract: COMPOSITE DROPOUT FUSE DEVICE             ABSTRACT:  A dropout type fuse cutout is provided having a high current limiting fuse section and a serially connected expulsion fuse section mounted on a conventional dropout toggle linkage arrange-ment so that fuse action by the expulsion fuse  section causes the cutout to dropout and pivot free of the upper terminal.  The current limiting fuse section may comprise a helically edge wound fusible member that reduces the terminal-to-terminal distance thereby reducing the length of the current limiting fuse section so that there is a very short external gap.  Further, because of the sequential occurrence of maximum voltage across the current limiting fuse section and the expulsion fuse section, each section experiences a unique voltage distribution that requires the utilization of insulating skirts on both fuse sections to maintain the external voltage withstand capabilities of the device even though the device is of sufficient overall length to be expected to provide an adequate dielectric path when contaminated or under wet conditions.

Abstract: ABSTRACT OF THE DISCLOSURE       Molten slag from a furnace is broken into granules by mixing with large quantities of water outside the furnace, thereby producing a slurry containing granulated slag, which can be used for example as a cement or ballast material. The slurry is introduced into a quenching tank from which part of the water is caused to overflow so that a thickened granu-lated slag slurry can be pumped from a lower part of the tank, where the slag granules are precipitated and stirred by cold water injected into the tank, this also bringing the slurry to a comparatively low temperature.  The thickened slurry is pumped to a sedimentation tank where the granulated slag is produced by removing water from the slurry, this water being combined with the water overflowing from the quenching tank and cooled before being returned to the region of the quenching tank to be mixed with the molten slag and in-jected into the quenching tank.

Abstract: AUTOMATIC CONTROL OF EXTRUSION RATE Abstract of the Disclosure The rate of extrusion of an elongated article from a dynamic extruder is measured and a measurement signal representative thereof is established. The measurement signal is then compared with a setpoint signal representing the desired extrusion rate to produce a control signal which is responsive to the difference between the measurement signal and the setpoint signal. The rate of introduction of polymer particles into the plasticization section of the extruder is automatically manipulated responsive to the control signal to maintain the extrusion rate at least substantially constant at the desired rate. The control signal can be adjusted to take into account variations in the temperature of the molten polymer entering the long land cooling die of the extruder.

Abstract: ABSTRACT OF THE DISCLOSURE        A trailer hitch and brake actuator having lower production costs and improved operation is provided. The housings of the actuator are of stamped, low cost construction, employing fewer separate pieces.  The actuator includes a rear component carrying a brake cylinder with a spring on the piston rod of the brake cylinder being engaged by a rigid member which is movable with a forward component and is connected directly with a shock absorber. The shock absorber is carried by the rear component and is parallel to the piston rod of the brake cylinder and to the movement of the forward component of the actuator.  The brake cylinder is located directly above the shock absorber to minimize the space required and accordingly enable the actuator to be reduced in size.  The forward component is of tubular cross section and is received in a passage of the rear actuator component and slidably carried thereby through plastic bearings.  The actuator also has a break-away lever employing an over-center linkage with the lever acting on the brake piston rod spring and moved to an over-center position by a flexible link attached to the towing vehicle in the event the trailer becomes separated therefrom.

Abstract: "ONE-WAY CLUTCH FOR AUGER AGITATOR"     ' ABSTRACT OF THE DISCLOSURE         A vertical-axis, automatic washing machine has a central drive shaft for oscillatably driving a first agitator portion with a clutch member splined thereto.  The clutch has downwardly-facing teeth having drive surfaces and slip surfaces.          An auger or second agitator portion coaxial with the first agi-tator portion has cooperating upwardly-facing teeth.  Upon a drive or forward oscillation of the drive shaft and first agi-tator portion, the drive surfaces engage one another to drive the auger portion in a stepwise rotation.  During an opposite rotation of the first agitator portion, the slip surfaces en-gage one another and, where the contents of the washer basket retards a reverse movement of the auger, the teeth will slip past one another, with the clutch member reciprocating verti-cally upon its splined connection.  An annular cushioning member placed between the clutch and the agitator parts cush-ions impacts between the teeth during such reciprocations by controlling the depth of tooth engagement.  Thus, noise other-wise normally produced during ratcheting of the clutch is sub-stantially reduced.

Abstract: Abstract of the Disclosure An acoustic system for measuring the speed of flow or current speed of a body of water employing a measuring path through the water which extends from one shore to the other in a direction oblique to the direction of flow of the water.  A triggerable measuring sound generator positioned on one shore transmits a pulse over the measuring path to a receiver on the other shore. The receiver produces an output which triggers the measuring sound generator to emit a subsequent pulse.  A measuring circuit evaluates the resulting pulse repetition frequency of pulses emitted by the sound generator and produces an output proportional to the flow speed of the water.
